• Abstract:
  The majority of Texas highway rest areas were built in the 1960's. The water and wastewater systems at these rest areas reflect the technology available at that time. This report summarizes the currents state-of-the-art technologies for water and wastewater sys terns at highway rest areas in the United States. Methods for determining rest area water demands, wastewater flows, pump sizes, storage tank volumes, and fixture requirements were explored. Various wastewater systems used at rest areas in outside states were evaluated. The two problems most frequently encountered in rest area water systems are inadequate water supply and/or water pressure. Water demand data for Texas rest areas is non-existent and thus water meters need to be installed at all Texas rest areas. Meters should separate the volume of water used in rest rooms from outside water demands at the rest area. For more immediate purposes, water demands can be estimated using the Zaltzman method. Ideal water pressure at rest areas is 40 psi with 20 to 60 psi being acceptable. Water system component sizing should be based on peak water demands. Rest area wastewater systems best suited for Texas, in order of preference, are (1) evaporative ponds, (2) overflow ponds, (3) overland flow or spray irrigation, and (4) evapotranspiration beds. Failed septic systems can be renovated using the systems listed above during rest area high use periods.
